I-NVIDIA Mellanox MSB7800-ES2F iyiswishi ye-Switch-IB™ esuselwe ku-2-based EDR InfiniBand eyinhloko, eyenzelwe ukuletha ukusebenza okuphezulu kwe-high-performance computing (HPC), izikhungo zedatha ze-cloud-scale, kanye namaqoqo okuqeqesha e-AI athuthukile. Ku-1U form factor encane kakhulu, lolu hlelo lokushintsha olulawulwayo lunikeza amachweba e-QSFP28 angavimbeli angu-36, ngalinye lisekela ukusebenza kwesivinini sentambo esingu-100Gb/s (EDR), okuholela kumthamo omkhulu wokushintsha ohlanganisiwe ongu-7.2 Terabits ngomzuzwana (Tb/s).
Isebenza nge-Switch-IB 2 ASIC eyinkimbinkimbi, i-MSB7800-ES2F yethula amakhono e-In-Network Computing ashintshashintshayo. Ngokulayisha imisebenzi yokuxhumana kusuka ku-CPU iye kunethiwekhi, kunciphisa kakhulu ukusebenza kwe-synchronization overhead. Inciphisa ukubambezeleka kube yimizuzwana engama-90 kuphela, iqinisekisa ukugeleza kwedatha okungenamkhawulo kwemithwalo yemisebenzi eminingi kakhulu yokubala.
Njenge-Switch Elawulwa Ngokugcwele, ifaka iprosesa ehlanganisiwe ye-x86 dual-core ukuphatha ukuphathwa kwe-subnet kanye nokuqapha kwenethiwekhi okuthuthukisiwe endaweni. Ngomklamo wayo we-P2C (Power-to-Connector) womoya, izinsiza zamandla ze-AC ezishintshashintshayo ezishisayo, kanye ne-chassis eqinile ejulile, yakhelwe imisebenzi ebalulekile yomsebenzi amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto. Kungakhathaliseki ukuthi ukhulisa ifu langasese noma wakha iqembu locwaningo elinabantu abaningi, i-MSB7800-ES2F inikeza ukuthembeka okungenakuqhathaniswa, ukusabalala, kanye nomkhawulokudonsa odingekayo ukushayela amabhizinisi esimanje aqhutshwa idatha.
Incazelo Yomkhiqizo
I-NVIDIA Mellanox MSB7800-ES2F iyiswishi yesigaba sebhizinisi esinobuningi obukhulu eyakhelwe ukuvumela ukuthunyelwa kwendwangu okusheshayo kwezindawo zesikhungo sedatha kanye ne-HPC. Njengeswishi ye-InfiniBand eyinhloko, inikeza ukusebenza okuhle kakhulu ngomthamo wokushintsha ongu-7.2 Tbps kanye nokubambezeleka okuphansi kakhulu okubalulekile kwekhompyutha yeqembu elikalayo. Ngamachweba enethiwekhi angu-36 anesivinini esikhulu ku-compact 1U form factor, yenzelwe ukuxhumeka kwamaqabunga aphezulu noma ukwakha amaqoqo anoma yiluphi usayizi, okwenza kube yisisombululo esifanele kokubili imisebenzi esabalele edingayo kanye nezinhlelo zokusebenza ezinkulu eziqhutshwa idatha. Iprosesa ye-x86 ehlanganisiwe ethuthukisiwe iqinisekisa ukuphathwa nokusebenza kahle, isekela ukuhlanganiswa okuqinile kwe-InfiniBand kanye nokukhula okungenamthungo.
Ihlanganisa amamojula wamandla amabili aphindaphindwayo, imojula yefeni eshintshashintshayo, kanye nokuhamba komoya okuhamba phambili, i-MSB7800-ES2F inikeza ukuthembeka okuhamba phambili embonini. Yakhelwe izindawo ze-NVIDIA Mellanox, ithuthukisa ukusebenza kahle kanye nokuguquguquka, inika amandla amaqembu e-IT ebhizinisi, abahlanganisi, kanye nabasebenzisi bokugcina kulo lonke elase-Asia, eYurophu, e-Afrika naseNyakatho Melika ngokusebenza okukhuliswayo.
Ukwakhiwa kwe-InfiniBand okuhlanganisiwe kwale switch kuqinisekisa izindlela zedatha ezitholakala kakhulu ezibalulekile emisebenzini yokugcina nokubhala ephezulu yanamuhla. Ifakwe i-RAM engu-4GB DDR3 kanye ne-SSD engu-16GB, iyakwazi ukusebenza kahle ngaphansi kwemisebenzi yesikhungo sedatha lapho isikhathi esiphezulu sokusebenza kanye nokusebenza okuqhubekayo kubaluleke kakhulu. Kungakhathaliseki ukuthi ungumsabalalisi, umhlanganisi wezinhlelo ezincane kuya kweziphakathi, noma umsebenzisi wokugcina odinga amakhono okuxhumana athuthukile, inhlanganisela ye-NVIDIA Mellanox MSB7800-ES2F yobuchwepheshe obunezinhlangothi ezimbili kanye nobubanzi bamachweba angu-36 inikeza isisekelo sokuxhumana kwengqalasizinda yesimanje ye-IT.
Okuvelele Komkhiqizo
1. 7.2 Tbps I-Aggregate Switching inikeza i-bandwidth enkulu engavimbeli ukusingatha ithrafikhi yedatha esindayo nokuqeda izithiyo zenethiwekhi.
2. Amachweba angu-36 100G QSFP28 Ukuxhumeka okuphezulu endaweni encane yefomu ye-1U, eyakhelwe inhloso yama-leaf nodes nama-clusters amakhulu.
3. I-Dual-Core x86 Management CPU: Isebenza nge-x86 dual-core processor ethuthukisiwe ene-4GB RAM kanye ne-16GB SSD ukuze isebenze kahle futhi iqine.
4. Ukubambezeleka kwama-90ns: I-Port-to-Port ephansi kakhulu. Ukusebenza okuhle kakhulu ngesikhathi sangempela, okulungele ukuqeqeshwa kwe-AI, ukulingisa kwesayensi, kanye nemithwalo yemisebenzi ezwela ukubambezeleka.
5. Amandla Aphindwe Kabili E-AC PSU: Amamojula kagesi aphindaphindwayo angashintshwa aqinisekisa ukusebenza amahora angama-24 ngosuku kanye nokuzinza okubalulekile embonini.
6. Umklamo Wokupholisa Okwenziwe Kahle Wokuhamba Komoya we-P2C: Ukuhamba komoya okuya ku-Power-to-Connector (ngemuva kuya phambili) kuhambisana kahle nokuphathwa kwe-aisle ejwayelekile yesikhungo sedatha esishisayo/esibandayo.
Izimo Zokusetshenziswa Komkhiqizo
Isikhungo Sedatha sinikeza ukushintsha okuqinile okungavimbeli okungu-7.2 Tbps kanye nokuxhumana okusheshayo kwe-InfiniBand, okwenzelwe ngqo izikhungo zedatha ezinkulu, ezibucayi ekubambezelekeni kanye namaqoqo amafu.
Izinsizakalo Zamafu: Ukwakhiwa kwamachweba angu-36 anabantu abaningi kwandisa kakhulu i-bandwidth yemisebenzi yamafu e-virtualized, kuthuthukisa ukusebenza kwawo wonke futhi kunciphisa izithiyo ze-I/O ngamaphesenti afinyelela ku-60.
I-Research Computing: Ukwakheka kwe-InfiniBand okulungiselelwe kahle kulungele i-High-Performance Computing (HPC), kusekela amaqoqo amakhulu wokubala ahambisanayo anezixhumanisi ezihambisanayo, ezisheshayo kakhulu.
